WILLIAM B. ALLBRIGH'I, OF CHICAGO, ILLINOIS.

CAECASS-BEATER.

Specification of Letters Patent.

Patented Dec. 141, 1915.

Application filed March 16, 1914. Serial No. 824,871.

To all whom it may concern.

Be it known that 1, WILLIAM B. ALLBRIGHT, a citizen of the United States, and a resi; dent of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carcass-Beaters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

The most successful type of beater used in carcass dehairing machines is the resilient loop heavy fabric beater provided with metallic scrapers. Practically-the only portion of the beater which depreciates or wears with continued use is the fabric loop, and the other parts of the beater may be again used when the fabric loop is renewed.

This invention relates to a fabric loop beater of an improved construction in which the length of fabric used to construct the loop is considerably less than that heretofore used, thus efiecting economy in the replacement thereof. 1 also greatly simplify the construction and assembly of the parts, readily permitting the same to be attached or detached from the machine without'inconvenience or loss of time.

It is an object of this invention to construct a carcass beater for use in hog dehairing machines wherein a relatively short loop of fabric is detachably connected upon metal arms,-which are bolted to one another around a shaft.

t is also an object of this invention to construct a carcass heater in which loops driving shaft with a separate looped beater disposed on each side thereof, the loops of said heaters being detachably connected upon metal arms which are clamped upon said shaft.

It is furthermore an object of this invention to construct a beater comprising a loop of heavy fabric detachably connected at its ends upon metal arms of unequal length, thus providing a, loop a leading side longer than the trailing side, with scrapers attached on said leading side and reinforc- 1ng members disposed rearwardly of said leading side to brace the loop as it bends.

It is finally an object of this invention to construct a resilient carcass beater comprising a pair of beaters oppositely disposed and clamped upon a driving shaft by similarly constructed interchangeable attaching means.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings: Figure 1 is a top plan v ew of a beater shown in horizontal position mounted upon a fragmentary portion of a shaft. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is a section on line 33 of Fig. 2. Fig. f is a section on line l -1- of Fig. 2.

As shown in the drawings, the beater is mounted upon a driving shaft 1, and consists of semi-circular clamps 2, which are exactly similar in construction and interchangeable, said clamps being held together bybolts 8, on opposite sides of said shaft. A curved attaching plate at, is integrally connected on one side of each of said clamps by means of an angled arm 5, and as clearly shown in Fig. 1, a reinforcing rib 6, is formed centrally on said clamps and merges into the arm to strengthen the structure as a whole. Ribs 7, are also provided on the other side of said clamps to receive the squared heads of the bolts 3, therebetween to prevent rotation of the bolts as the nuts are tightened up. Adjacent said ribs 7, is an abrupt right angled web 8, also formed integrally with said clamps, and integral with said web 8, is an outwardly directed rearwardly curved rigid reinforcing arm 9. A loop of relatively stiff fabric 10, is bolted at one of its ends between a clamping plate 11, and'a relatively stiff short piece of fabric 12, which rests upon the inner portion of said reinforcing member 9, said members all being rigidly held to said latter member by means of bolts 13, extending therethrough. Ribs 14, are formed on the surface of said member 9, to receive the squared heads of the bolts 18, to prevent rotation thereof when the nuts are tightened. The other end of said fabric loop is clamped against a flexible reinforcin strip 35, upon said flat plate 42, by means of bolts 16. Riveted or secured in any suitable manner upon the leading side of the loop 10, are metallic scrapers 18, in this instance five being shown symmetrically arranged, but, of course, the arrangement and number is subject to variation without departing from the principles of the invention.

The operation is as follows: When it is desired to adjust the beater upon the shaft merely one pair of the bolts 3, are loosened, thus permitting the heaters to be rotated into a desired position or moved longitudinally upon the shaft, as desired. In dismounting a beater from the shaft the bolts 3, are removed and one set of either the bolts 13 or 16, whichever are most convenient for the purpose, or if the end 1, of the shaft is free, of course the beater may be moved longitudinally and taken off at the end thereof. However, one of the principal points of advantage in this particular beater is the fact that an economy in the quantity of fabric is attained. The means of attaching the beater to the shaft is extremely simple, and the flexible reinforcing members 12, and the rigid reinforcement members 9, prevent an abrupt bending of the fabric at any one point which would tend to break the same and soon render it unfit for use.

I am aware that various details of construction may be varied through a wide range without departing from theprinciples of this invention. I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described interchangeable clamps adapted to be secured in opposed relation to one another on a shaft, fabric beater loops having their ends connected to the adjacent ends of said clamps with the leading side of the loops longer than the trailing side, and rigid curved reinforcing members one each integral with said clamps and positioned behind the leading side of the loops.

2. In a device of the class described beater loops, scrapers riveted, to the leading side of each thereof, clamps adapted to be secured in opposed relation to one another on a driving shaft, said loops adapted to have their ends connected to the adjacent ends of said clamps on opposite sides of said shaft, and reinforcing members integral with said clamps and positioned behind the leading side of said loops.

3. In a device of the class described beater loops, clamps therefor secured upon a shaft, said clamps similarly constructed and interchangeable with one another, and a pair of attaching arms on each of said clamps for said loops, the distance from the shaft to the points of attachment of said loops to the arms on the trailing sides of said loops being greater than that to the points of attachment on the leading side, thus providing a longer length of fabric on the leading side of the loop.

4:. In a device of the class described clamping members in opposed relation to one another, loops having their ends attached to the adjacent ends of said members, said loops having the leading side longer than the trailing side, scraping elements secured on each of said loops on the leading side thereof, and reinforcing members on said clamping means within said loops to hinder the bending movement of said loops.

5. A beater of the class described embracing a shaft, loops of flexible material,

and a pair of clamping members secured on said shaft with the adjacent ends of said clamps each secured to one end of one of said loops.

6. In a device of the class described a pair of contacting clamps, a looped beater connected to adjacent ends of said clamps at one side of the shaft, and scraping members secured on said beater, the points of connection of the ends of the looped beater with the respective clamps being such as to form a loop with its leading side longer than the trailing side.

7. In a device of the class described a pair of beaters, a pair of similarly constructed interchangeable clamping members, each member comprising a semi-circular portion, an attaching arm. integral therewith on one side of said semi-circular por tion for attachment of one end of one of said beaters thereto, another attaching arm disposed on the opposite side of said semicircular portion but of shorter length than said first arm for receiving attached thereto one end of the other of said beaters whereby the respective ends of said beaters are connected to said respective arms of said clamp ing members, and means for securing said beaters to said arms.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses. I

WILLIAM B. ALLBRIGH'I.
